Improvement in oil-ejectors



UNITED STATES ERASTUS OROOKER, OF

BUFFALO, YORK.

IMPROVEMENT IN OIL-EJECTORYS.

Specification forming part of Letters Patent No. 47,399, dated April 25, 1865.

To all whom, it may concern:

Be it known that I, ERAsTUs CROOKER, of the city of Buffalo, county of Erie, and State of New York, have invented a method of preventing the condensation of steam in steam-` pipes used in elevating oil from deep petroleum-oil wells; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, forming a part of this speciiication, in which` Figure I is a vertical section of a steam oilejector, which is located at or near the bottom of an oilwell, and the non-condensing steampipe by which the same is supplied withsteam. Fig. Il is a cross-section of same.

The nature of this invention relates to covering the steam-pipe by which the steam is suppliedto the ejector with gutta-percha, india-rubber, or other suitable material, so that the steam-pipe shall not come in contact with oil or water in the well and thereby keep the steam-pipe hot,so that the steam will not condense therein. Y In all the petroleum-oil wells, so far as my knowledge goes, where an effort has been made to raise or elevate the oil by an application of steam through ejectors there has been a great difficulty in getting the steam down to any considerable depth by reason of the low temperature ofthe wells, causing the steam to condense in the pipe before reaching a sufficient depth to operate the ejector. My improvement ai'ords aremedy for this difflculty. The gutta-percha covering eiectually protects the pipe from the effectsofthe cold water, air, and low temperature of the wells, and allows the steam to be forced down the pipe to any required depth without any material condensation or loss of pressure; and hence my improvement will render the use of entirely successful. j

The ejector consists of a suction-barrel, A, surmounted by a chamber, B, containing a charge into the conical nozzle. D represents the oil-discharge pipe,` opening into the top of the chamber B `directly over the mouth of the conical nozzle. This pipe extends up to the leads down into the well side by side with the end to an appropriate boiler for generating steam to operate the ejector.
